【Overheat Protection and Durability】The bottom of the stove fan incorporates a double metal, lifting slightly when the temperature reaches its maximum of 350°C, thus protecting the motor and module from overheating and extending the life of the fireplace fan. Monitor temperature fluctuations during use. The magnetic thermometer generally has a temperature difference of about 10°C. 【Energy Saving and Environmentally Friendly】A high-quality fireplace fan can save you 37% on fuel and electricity costs. No batteries or recharging required, it converts the heat from the fireplace into kinetic energy to diffuse heat. Stove fan typically operates between 80°C and 250°C, rotating at about 55°C-75°C, with peak efficiency at 250°C-300°C. 【Ease of Use】Use a thermometer to measure the temperature, in contact with the location of the fan, and then use it directly within the range of 80°C to 300°C. The thermometer can be placed near the fan to monitor the temperature. The wood stove fan is
